FAUCET-VALVE.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed February 20, 1914, Serial No. 820,070. Renewed July 24-, 1915. Serial No. 41,799.

To all whom it may concern:

Be it known that I, THOMAS F. PAYNE, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Faucet-Valves, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, which form part of this specification.

By my invention I aim to provide a new and improved construction in faucet valves, whereby a positively acting and readily adjustable valve mechanism is afforded and in which the parts are so arranged that the said mechanism may be removed intact from the casing of the valve. I also aim to provide other new and improved features of construction, as will be hereinafter more fully described and pointed out in the claims.

I will now describe my invention, referring to the accompanying drawings, so that others skilled in the art to which it appertains may understand and construct the same, it being premised however, that changes may be made therein without departing from my invention.

Figure 1 is a vertical sectional view of a faucet valve embodying my invention, the spout being shown in elevation; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is an enlarged fragmentary vertical sectional view of the upper end of the faucet valve showing modified means of valve stem adjusting mechanism; Fig. l is a plan view of the nonrotating washer or abutment employed in the modified structure shown in Fig. 3; Fig. 5 is a section on the line 5-5 of Fig. 3; and Fig. 6 is a fragmentary sectional view showing modified manner of forming the lower end of the valve stem.

Referring to Figs. 1 and 2, the reference numeral 2 indicates the casing of a faucet valve having the usual inlet 3 and outlet 4; leading through a spout 5. Intermediate the inlet and outlet the valve casing is formed with the usual port 6 controlled by a valve 7, the valve stem 8 of which is mounted against rotation as by being square finished at 9 for reception in a square bore of a sleeve member 10 that is non-rotatably clamped to the upper end of the casing 2 by means of a nut member 11; the upper portion of the valve stem, which passes through the member 11, preferably being round in cross-section. The valve 7 1s shown as being screw-threaded to the stem and carrying an adjustable collar 12 between which and the member 10 is interposed a spring 13 that serves to normally urge the valve to closed position upon a seat 14 surrounding the port 6. The stem 8 also extends upwardly through a head portion 15 of an operating handle 16 and between the head 15 and the member 11 are interposed balls or rollers 17 that are disposed in double acting cam ways 18 and 19 formed respectively in the top of the member 11 and the lower face of the head 15. It will be noticed that the member 11 is provided with an upstanding wall portion 19 surrounding the cam ways 18, of such height as would prevent accidental dislodgment of the balls should the handle of the faucet be removed for any purpose; the head 15 being provided preferably with a flange or skirt 20 that dependingly surrounds the wall 19. Carried by thetop of the stem is an abutment disk or washer 21 which is mounted against rotation on the stem as by having its bore provided with a flat face 22, as shown in Fig. 2, which fits a flat finished face on the stem at that point, and interposed between the washer 21 and a top face of the head 15 of the handle is a washer 23 preferably of fiber or any other suitable material. Screw-threaded to the top of the stem is an adjustable cap nut 24 through which passes a lock screw 25 into engagement with the stem. By means of the cap nut 24 such adjustment of the stem with respect to the operating handle may obtain as permits of seating of the valve without binding of the washers 21 and 23 or the nut 24: upon the handle. In other words, while the arrangement shown permits of positive operation of the valve, the space between the lower end of the cap nut 24: and the washer 21 is such as to permit of perfect seating of the valve upon the seat 14:. After the nut 24 has been adjusted it may be locked in positionby the screw 25 the threads of which are preferably of a pitch difierent from that of the stem engaging thread of the nut 24 so that any tendency to rotative creeping of the nut 24 is opposed by the screw 25 or vice versa.

Upon turning of the handle 16 the cam faces act upon the balls 17 in such manner as to bring the washer 21 into abutment with the-lower end of the cap nut 24; the

effect of which is to force the stem of the valve upwardly, bringing the valve member 7 away from the port 6, against the tension of the spring 13. Upon release of the handle the spring returns the valve to the seat. It will be seen that the cap nut is of such character as to present a strong abutment to the action of the handle or the washer 21 thereon, and is securely locked against movement.

The upper part of the handle is provided with a cap piece 26 carrying an index head 27, and this cap piece is preferably locked by means of a set screw 28 carried by the handle, so that when the faucet is placed in position for use, the index but-ton or head may be properly positioned and locked against shifting.

In Figs. 3 and I I show a modified manner of mounting the abutment washer of the stem against rotation thereon and for looking the cap nut 24 to the stem. The stem portion is provided with a plurality of flutes or longitudinal recesses 29 which receive the projecting bosses 30 carried by the washer or disk 21'. The cap nut 24 which is mounted at thetop of the stem is provided with a screw 25 the lower end or shank 31 of whichis adapted to be received by one of the recesses 29 of the stem and a registering recess 32 in the cap nut. By providing a pluralitv of recesses 29 suitable adjustabilitv of the cap nut 24 is afforded while still preserving the locking feature.

In Fig. 6 I show the valve 7 as being carried integrally by the lower end of the stem instead of being separately formed and screw-threaded to the stem as shown in Fig. I; the lower end of the stem in this instance carrying the adjustable collar 12.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a self closing faucet valve, a casing having an inlet and a discharge outlet and a port intermediate the inlet and outlet, a movable valve for controlling the port. a re movable sleeve member fixedly held in the casing and having a bore provided with a longitudinal flat face, a stem for the valve, disposed in the sleeve and provided with a fiat face portion coacting with the flat face of the sleeve, for preventing rotative creeping of the stem, and means associated with the stem, for operating the valve; the sleeve being adapted to limit the movement of the valve.
